AbstractRamadan fasting is accompanied by an increase of the gastric acidity over 24 hours especially in the daytime. Gastric acidity is maximal at the end of the fasting day. So, a patient with duodenal ulcer is exposed to a high risk of disease reactivation. The frequency of ulcer complications is statistically higher during the month of Ramadan than the rest of the year. The frequency of the upper gastrointestinal hemorrhage is multiplied by 2 and perforation by 4. Helicobacter pylori eradication does not seem to play a role in the occurrence of these complications, particularly the perforation. The patient with duodenal ulcer can fast without risks while using a proton pump inhibitor if the ulcer is healed and H. pylori is eradicated. Ramadan fasting seems to us inadvisable when duodenal ulcer is active, but large prospective studies are needed.Copyright © 2012 Elsevier Masson SAS. All rights reserved.
